A butterfly valve (30) in which an actuator (38) is secured to the plate (36). The actuator (38) is carried with the plate (36) when the latter moves. The plate (36) may be revolvable and translatable relative to the shaft (42). The actuator (38) may be used to open and adjust a pilot valve (94) secured to and carried with the plate (36), and to revolve or translate the plate (36) relative to the shaft (42) in order to vary hydrodynamic torque exerted on the plate (36).
